[PATCH 10/10] ASoC: lpass-wsa-macro: add missing test

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

cppcheck warning:

sound/soc/codecs/lpass-wsa-macro.c:958:6: style: Variable 'ret' is
reassigned a value before the old one has been
used. [redundantAssignment]
 ret = wsa_macro_set_prim_interpolator_rate(dai, (u8) rate_val, sample_rate);
     ^
sound/soc/codecs/lpass-wsa-macro.c:946:6: note: ret is assigned
 ret = wsa_macro_set_mix_interpolator_rate(dai, (u8) rate_val, sample_rate);
     ^
sound/soc/codecs/lpass-wsa-macro.c:958:6: note: ret is overwritten
 ret = wsa_macro_set_prim_interpolator_rate(dai, (u8) rate_val, sample_rate);
     ^

set_mix_interpolator_rate can return -EINVAL, add a test and bail on error.
